CARBON REMOVER.

Application filed January 18', 1921; Serial No. 438,206.

To all whom it may concern:

Be it known that I, J OHN' F. SMERsoHNIK, a citizen of the UnitedStates, residing at VVilkes-Barre, in the county of Luzerne and State ofPennsylvania, have invented certain new and useful Improvements in a Carbon Remover, of which the following is a specification.

This invention relates to carbon removers and more particularly to anelectric motor operated brush for the purpose of scraping and brushingcarbon from the interior of the cylinders of hydro-carbon motors.

One of the objects of the invention is to provide an electrically drivenbrush arranged so as to be conveniently inserted in the cylinder of amotor so that the brush'may engage the walls of the cylinder and berapidly rotated to scrape and brush the coating of carbon from thesurface without injury to the surface of the motor or cylinder.

Other objects will appear upon consideration of the following detaildescription and accompanying drawings wherein Figure 1 is a sideelevation of the apparatus constructed in accordance with my invention,

Figure 2 is an enlarged view of the brush element on the gearingmechanism for driving the same,

Figure 3 is an edge view, of the mechanism shown in Fig. 2

Figure 4 is an elevation of a slightly modified from of the invention,parts being broken away to show the interior construction,

Figure 5 is an end elevation, and

Figure 6 is a horizontal section taken approximately on the'line 6 6 ofFig. 4.

Referring to the drawings by numerals, and particularly to Figs. 1,2 and3, the electric motor 1 is provided with a handle 2 and a hand grip 3whereby the operator may hold the apparatus conveniently for thrustingit into the cylinder of a motor. Attached to the motor casing is asleeve 4 through which a drive shaft extends. The drive shaft is mountedin suitable bearings and has its outer end equipped with beveled gear 6adapted to mesh with a large bevel gear 7 on a transverse shaft 8 whichextends through the gear casing and is journaled in opposite sides ofthe casing. The shaft 8 is also provided with a spur gear 9 in mesh withan auxiliary drive pinion 10 on the brush shaft 11. The shaft 11 ismounted in suitable bearings and has the brush element 12 mountedthereon which consists of a pair ofdisks 13 having the bristles of thebrush mounted therebetween. The train of gearing and brush element aremounted in the casing 14, of such configuration that the portion housingthe briish is offset from the handle. The brush element 12 is of adiameter large enough to extend outwardly from one side of the offsetportion of the casing as shown in Figs. 1 and 2 of the drawings and itwill be obvious from this constructlon that when the motor is energizedthe shaft 5 will be rotated so that the gearing mechanism will operateto rapidly rotate the brush 12. While this is being done, the brushelement may be thrust into the motor cylinder and the bristles will bein contact with the wall of the cylinder to cause the carbon to bescraped and brushed therefrom.

The gear casing 14.- is removably mounted on the end of the sleeve 4 andit will be observed from Fig. 2 that the entire gearing mechanism may beremoved from the end of the device, and a fan or other suitable blowingmeans may be mounted on the end of the shaft and the shaft then operatedby the motor to blow the carbon from the interior of the cylinder afterit has been re moved by the brush.

Referring particularly to Figs. 4, 5 and 6 wherein a modified form ofthe invention is illustrated, it will be noted that the sleeve 4 has agear casing 16 attached thereto, and the end of the shaft is providedwith a worm 17 adapted to mesh with a worm gear 18 on a transverse gearshaft 19. This gear is in mesh with a larger gear 20 on the brush shaft21 which extends transversely through the gear casing and has the brushmember 22 mounted thereon. This form of the invention operates in thesame manner as the above described form except that it is driven by aworm gear instead of by a bevel gear. The gear casing is offset withrespect to the central portion of the sleeve 4 so that the brush element22 is disposed in a position to be thrust against the inner surface ofthe wall of the cylinder whereby the carbon may be conveniently removedwhen the motor is energized.

Minor changes may be made in the details ef construction withoutdeparting from the set portion, and a train of gearing in said spirit ofthe invention or the scope of the casing connected with said motor shaftand claim hereunto appended. said brush, said motor having means thereonWhat is claimed is for handling said device. k 5.
